In an ASP. NET page, the query is often used to display the results, there are a lot of query conditions of the text box, then also use the empty button, is to clear the criteria of the query text box or other control.
Here are two implementations of the more empty buttons used.
There are two ways of doing this:
First, the control is set to the initial state, such as the text box is set to empty, drop-down list of settings asked to select an item, and so on;
The second is to return the entire page to its original state.

In both ways, the first is more cumbersome, but the use is more flexible; the second is relatively simple. You can choose according to your actual use situation flexibly.
